Hello

Im looking to do a study on how we evaluate sales ppl by their sales. usually, there is becoming a wide gap is what's reported and what transpires.

there are approx 175 employees, and so is it a fair estimate to use my sample size of 10%? yes i realize if i do a true sample size (stats), using confidence interval and standard dev.; i get a sample size of 121 based on my population of 175.

so i guess what im asking is, is 10% of the population a sufficient sample size to based a study on? i really appreciate the input thxs.
